I don't think that is correct. I think we'll hear when it starts. "scheduled to start" is not a binding statement.
What did we have...sevenish progress PRs on the B-ABSSSI trial which included start, 20% enrollment/dosing, enrollment complete, dosing completed, etc.?
Obviously with a drop like today he would issue a PR today or tomorrow stating the trial has started and enrollment is in progress if he could.
